Answer 1

Answer:2%

Explanation:

Answer 2

ANSWER:

The correct option is c) 2%.

EXPLANATION:

     The formula for the "area of a rectangle" is Length × Breadth. The measurement of error for a quantity which is calculated by multiplying two quantities is found out by adding the individual errors multiplied with the number of times the particular quantity is multiplied.

     So, the formula to calculate the error in the area will be (Error in length) ×1 + (Error in breadth)×1. So the answer will be (1% × 1) + (1% × 1) = 2%.
